We just launched #earthtweet, a campaign to raise awareness of the fight against climate change in the days leading up to Earth Day (April 22) – and beyond.

Here’s the idea: #earthtweet uses Twitter – the booming social network of the moment – to bring together tips, news, information about events, and anything else that’s relevant to solving our climate problem. (Yeah, most of us here at Brighter Planet have caught the Twitter bug – it’s the most useful, vibrant, and fun social network we’ve seen to date.)

If you’re already on Twitter, all you have to do is tell us what you are doing – today – for the planet. Just make sure to use the tag #earthtweet somewhere in each item you’re sharing on Twitter, so everyone else can find it. We’ll also be giving away some eco-friendly prizes throughout the campaign, so follow @earthtweet to stay posted.

If you’re not yet among the converted, this is a perfect opportunity to give Twitter a try. Twitter is like CB radio, but for text messaging – it’s a great way to stay connected to friends, family, and as many other people as you like. Sign up and then you can “follow” @earthtweet and @brighterplanet!

In the last few months we’ve seen people achieve amazing things through collective effort on Twitter. Some examples:

Last Christmas, a TVA coal-burning power plant spilled millions of gallons of toxic coal ash into an East Tennessee river. Advocates on the ground – with support from Twitter folks all over the country – used Twitter to report on the immense scale of the disaster. The buzz grew loud enough that the sluggish national media finally began to cover the story; since then, the Obama administration has made clean-up of thousands of dangerous coal-ash ponds all over the nation part of its agenda.

Well, we want some of that action! We really hope that #earthtweet can make some noise about doing one’s part to solve the climate problem. It’s really up to all of you – #earthtweet will go exactly as far as you take it.

Have a ball with it. You’ll find badges, a widget, and temporary Twitter avatars available at http://earthtweet.com.
